Remove MPEG TS stream filtering based on AudioCapabilities.
Pass AudioCapabilities to MediaCodecAudioTrackRenderer so it can choose between
passthrough/raw and decoding for AC-3 tracks.
On NVIDIA Shield, recreated passthrough AudioTracks have incorrect playback head
positions, due to shared state with the previously destroyed passthrough
AudioTrack. Calling AudioTrack.flush() before AudioTrack.release() ensures this
state is cleared.
This is a safe change so I have not made it a device-specific workaround. The
combined time for flush and release is less than 10 ms (with flush normally
taking less than two ms).
Improve Mp4Extractor test.
Add support for Xiph lacing in Matroska files.
Add support for EBML lacing in Matroska files.
Handle the initial sticky intent for HDMI audio plug.
When a passthrough AudioTrack is replaced (due to seeking) the new one behaves
as if it is still emptying data from the old one, with its playback position
advancing until it runs out of data.
Data written while the 'old' AudioTrack was emptying would be discarded, so
avoid writing to the new AudioTrack while the old one is still emptying.
Also avoid using AudioTrack.getTimestamp with passthrough tracks, as this causes
the playback position to jump to a position that breaks audio/video
synchronization.
This works around an issue the audio track continues to play audio data written
after calling AudioTrack.pause(), which breaks rebuffering behavior (as video
can never catch up if audio continues to be consumed, in some circumstances).
Also don't increment the timestamp wrap count if the track is paused, to work
around an issue where the playback head position jumps back to zero after the
AudioTrack position jumps back to zero.
The OMX component needs to be configured with a format that has a
MIME type of audio/raw. Remove Ac3PassthroughAudioTrackRenderer,
which is no longer used.
- Workaround issue where video may freeze whilst audio continues
on some devices that have entered bad states.
- Fix wrap-around for playbacks lasting more than 27 hours.
- Target 4x the minimum specified by the framework.
- Impose a minimum duration (250ms).
- Impose a maximum duration (750ms, or the minimum
specified by the framework if that's larger).
I've removed the ability to specify the multiplication
factor, since the underlying implementation is getting more
complicated, and we should really be able to figure this out
internally.
- Handle read returning NOTHING_READ for AC-3 streams.
- Remove extra checks for the audio track being initialized.
- Call isInitialized() instead of checking audioTrack != null.
ac3Bitrate is set only after the first buffer is handled, which meant that
getting the playback position would cause a divide by zero before then.
When playing back AC-3 content, the ac3Bitrate will always be set after the
first buffer is handled, so return a 0 position if it is not set.
AudioTrack contains the portions of MediaCodecAudioTrackRenderer that handle the
platform AudioTrack instance, including synchronization (playback position
smoothing), non-blocking writes and releasing.
This refactoring should not affect the behavior of audio playback, and is in
preparation for adding an Ac3PassthroughAudioTrackRenderer that will use the
AudioTrack.
